What loads will be applied to this tube?
Think "main spar". The cables going to the wing attach to each end of the tube.
It is mainly a tension load. Tube is installed in composite structure side walls,
with 9-10 layers of BID to reinforce side wall. There should not be any "turning"
loads. I can get a bit paranoid about things. Sometimes that is good.

My current thoughts:

Don't worry, it is not an issue.

Drill tube, install pins/bolts, then bond.

Drill tube, install without bolts, then re-drill fiberglass to install bolts.
